74130-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74130-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,3 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74130-40:
(7*7)+(6*4)+(5*1)+(4*3)+(3*0)+(2*4)+(1*0)=98
98 % 10 = 8
So 74130-40-8 is a valid CAS Registry Number.
